" vent the escape of smoke and obnoxious gases into the atmosphere.

Another'object of theinvention is to provide a construction in which relativel large volumes of smoke may be quickly' and thoroughly treated by using a minimum amount of water. l y

The invention is embodied in a constructin in which the end of ,the'stack is open to thev atmosphere.Y The smoke, however,l is

ldeflected. b takin advantage ofthe fact that it-ten Y vto f o ow the h1 hv side of an obstruction or the like. By leflecting the smoke to one side of the stack, it may be i drawn down an adjacent condenser or smoke consumer b `means of a power driven fan.

Tllsmoke is next treated vith wateriE h the accom an g rawi ave illustrated one ,empboilniient' of mylgmvention,

"Fig.'2 is a sectional elevation of the same on an enlarged scale with parts :roken away.

Fig. 3 is a vertical secticnai view on the line 3-3 of Fig. 2, looking in the direction of the arrows. In the embodiment of the invention here illustrated, the stack 1 is shown as s uare Aend to allow the smoketo l in cross section and built up -of `bric in the usual manner. The stack .may communicate at the lower end Awith a furnace from which the products of combustion and smoke may escape with the obnoxious gases through the stack. The stack is o en at its upper issue there- `from, So as n ot to interfere with the natural draft through the stack.

My attachmentcomprises a condenser 2 supported in part by Aa hook 2* at its upper endlfitting over the upper edge of one side of the stack. As clearly shown in Fi l.

this condenser' extends substantially rom" Specication of Letters Patent.

with the sides of the Astack at right' angles to the portion 3. These triangularsides are attached to the upper edges of these sides of the stack and support the condenser in part. The projecting portion 3 and sides 4 constitute an'open to conduit connecting the stack with t e con enser. As the smoke and gases issue from the stack tle projecting port1on3 ofl the condenser 2 exerts an attraction upon thesmoke, tendin to cause the 14same2 vto be delectedto the rig n t, looking at ig.

,'Mounted within the condenser '2 at the outer side thereof and atk a point' sli htly below the upper end of the stackis a an 5 adapted to rotate lin the direction o f the arrow to draw the deflected smoke down throu h'thecondenser 2. The vfan y5 is fixed to a condenser and is po p the s rocket whee 7, sprocket chain 8 and s nlfiled within the stack or elsewhere. and

by means of the belt 11. It is to be understood, however, that I do not.4 intend tolimit myself to an particular means orsource of ower for iving the fan'. The power,

- owever, must be suihcient to cause the fan to draw substantially all the deilected smoke into the condenser, and assist in deecting it In order to prevent updraft resulting from the rotation of the fan I have provided a suitable deflector 12,-which pro]ects .inv

imperforate, whereb water issuing therefrom will be but not upwardly, thereby keeping p dryl and preventing 'the sp ashing of :the water. A pipe 17 of reduced diameter communicates with the pipe 14 and is con,- nected with any suitable source of water suply. The water mixes with the smoke, con ensing the saine, and dissolves and cleans.

The extreme lower end of the condenser is directed outwardly horizontally, as indicated at 19, Fig. 1, an provides la re- `2() therethrough. f In order .to avoid back pressure within the condenser 2-and the faultyI operation of pressure within the attachment. `For this` I. u n the horizon the attachment, there has been provided a device `for automatically controlling the purpose a valve 21. ivoted at 22 is mounted y teylfextendingportion 19. valve is contro ed b the pressurefof when ure air or tgas the con enser2,V whereby,
